TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed July 8, 1905. Serial No. 268,777.

' citizen of the United States, and resident of Bridgeport, in thecounty of Fairfield and State of Connecticut, have invented certain newand useful Improvements in Type- Writing Machines, of which thefollowing is aspecification.

This invention relates to improvements in the type actionsof typewritingmachines, it being especially applicable to visible writing machines ofthe style called front strike machines.

The object of the invention is to so impro-ve the construction of thetype actions as to relieve all of their parts from injurious torsionalstrains, to. equalize the depressions of the finger keys, and to secure.other benefits affecting .the operation of the. mechanism, and includesthe provision ofmeans embodied in the type bars and type bar rest forpreventing any of the type barsfrom rebounding into the path of another.

This invention consists of all the various; features of construction,combinations and; arrangements of parts, which are hereinafter describedand specified in the appended claims.

On the accompanying sheets of drawings, in which like reference numeralsdesignatelike parts in different views, ,Figure 1 is a side andsectional elevation of portions of a front-strike typewriting machine,including mechanism representing the invention;

Fig. 2 is a front and sectional elevation of some of the same and otherportions of this machine, certain connecting links being indicated bysingle lines; and Fig. 3 is a lan of some of the finger keys and a part0 the mechanism operative thereby to actuate the type bars, the singlelines at the left of the devices which are fully shown in plan,illustrating connecting links.

The frame of the machine is composed of a rectangular body 1 on whichare posts 2, and of a top-plate 3 fastened on the posts 2. The top platehas in it an opening 4 through which the type-bars move toward and fromthe platen 5. A type bar segment 6 is secured in the frame under thefront of the platen. It may be attached to the top.

plate by screws 7 passing through lugs 8,

formed on the ends of the segment, into threaded holes in the top plateas appears by Fig. 2, or may be confined by other means on four axes 13,14, 25 and 26.

lies in a groove in the segment and passes through all of the type bars.The type bars normally extend toward the front of the machine from thesegment to a type bar rest 12, by which their front ends are supported.Each type bar is movable on its pivot from its normal position to itsprinting position, the type bar which is shown in Fig. 1 beingrepresented by dotted lines in that figure in its printing position.

In the front part of the frame of the machine are fixed two round crossrods 13 and. 14, whose axes are parallel to the axis of, the platen andin a vertical plane. These rods are attached at their ends to the sidesof the frame. Two series of parallel angular levers 15 and 16 on whichare formed hubs 17 and 18, are loosely mounted on the rods 13 and 14,the levers being arranged in' pairs as shown, each of the levers 15being over a lever 16. To each of the forwardly projecting arms of eachpair of these levers, these arms being of equal length, is pivoted anupright link 19, having an extension on which is a finger key 20. Theextensions'of the links are properly formed to secure the arrangement ofthe finger-keys in banks, the extensions 21 on which the finger keys ofthe uppermost bank are mounted being prolongations of the links on whichthey are formed, and the other extensions 22, 23 and 24, projecting(litlerent distances in front of the links, in rows of differentheights. Since the lovers 15 and 16 are parallel .and the axes of thepivots 25 and 26 are equally distant from the vertical plane containingthe axes of the rods 13 and 14,'th levers of any pair may be turnedtogether on their pivotal -axes by depressing the fingerkey connectedwith them and each'link 19 turns To the rear ends of each pair of theparallel levers described is pivoted an upright link 27, comprisingupper and lower arms 28 and 29 which project in front of the uprightportion of the link and are pivoted respectively to the upper and lowerlevers of the pair by pins and 31, the upright portions of these links27 being behind the vertical plane containing the axes of the rods 13and 14, and lying normally close to the type bar rest 12. The links 27therefore are likewise arranged to turn on four axes, the fixed axes orpivot rods 13 and 14 and the movable axes or pivots 30 and 31. Thoselinks 27 which are in front of the middle portion of the type barsegment are provided with extensions 32 at their lower ends, and each ofthe two links at the ends of this series has on its upper end anextension 33. Connecting links 34 are ivoted at their front ends to theupright llnks 27 by pins 35, and at their rear ends to the type bars bypins 36. The front ends of the connecting links are pivoted to theupright links at elevations which progressively increase from the middleto the sides of the system of type actions. To each connecting link 34is attached a restoring spring 37, which is also attached to a curvedcross bar 38 fixed under the typeloar-segment.

The operation of the type actions described is indicated by dotted linesin Fig. 1, which represent the positions of the parts of one of the typeactions at the end of a printing movement of the type bar. lVith thedepression of the finger key the angular levers are turned on theiraxes, the pivots 30 and 31 being carried toward the front of the machineon arcs whose chords are substantially horizontal, and the link 27 isdrawn forward, pulling with it the connecting link 34,'the result beingthat the type bar. is swung to its printing position. It will beunderstood, since four of the pivotal axes of every type action areparallel to one another and the links 34 are nearly horizontal andconverge but slightly from the links 27 to the type bars, that. onlysmall torsional strains will be produced either at the sides of thesystem or else where, and it will also be seen that the dip of eachfinger key will substantially equal that of every other, forsubstantially equal movements of the links 27 are required to actuatethe type bars, and that the faces of the linger keys are constantlyhorizontal.

The type bar rest 12 is fixed in its relations to each of the type barpivots. In 1nachines in which the type bar segment is movable toward andfrom the platen, the type bar rest is to be attached to supports 46projecting from the segment. The face 39 of the rest, and that part 40of the edge of the type bar which makes contact with the rest, arepreferably formed and arranged as represented in Fig. 1 of the drawings,but it is not necessary that the form of either the rest or the edge ofthe type bar should be nreeisely as shown. Their relations are to besuch, however, as

to render the angle of incidence of the type bar on the rest a largeacute angle, whose complement is equal to the angle included by thefaces of a wedge, and consequently to subject the type bar and its pivotto pressure acting lengthwise of the type bar, when the latter strikesthe rest on returning to its normal position. The face 39 of the rest isshown in the form of a section of the surface of a blunt cone, whoseaxis is on a horizontal line 41 cut-ting the platen at the printingpoint, and whose apex is at the point 42 on the line 41, in front of avertical plane parallel to the axis of the platen and cutting thetypebarrest. The base of this cone is, therefore,

vertical and forms with any of the ele the lines' 43 and 44 intersectingeach other a at the point 45. This angle of incidence therefore isconsiderably greater than an angle of forty-five degrees, and itscomplement, represented by the lines 42 and 43, is equal to the angleincluded by the faces of a wedge. By subjecting the type bars topressure acting lengthwise thereof as explained, each of the type barsmay be prevented from rebounding into the path of another even when themachine is rapidly operated.

Various changes may be made in the mechanism above described withoutdeparting from the invention herei'n set forth and claimed.
